Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe without a median groove, with eight scattered adnotaular setae. Mesoscutellum with weak reticulation, meshes elongate; without a median groove; submedian grooves indistinct, running close to and parallel with lateral margins of mesoscutellum; anterior pair of setae situated medially. Dorsellum with weak sculpture and shiny. Propodeum with triangular median carina; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation; hind coxa with a carina along posterior margin in lower half.
